SLICE NANO Stack Battery

Certain details are not listed in the data sheet or in the user's documentation. Additional details are described here. The SLICE NANO Stack Battery is designed to provide a backup power to the stack in case of power loss.

It is not designed to provide primary power

Voltage to the base must be greater than 11Vdc. Run "Diagnostics" to verify your base input voltage. There are protection diodes in the Base that will drop ~0.5Vdc of your input power. A 12Vdc supply is recommended

The battery will not charge at elevated temperatures. The stack battery uses a temperature sensor to prevent over-charging. Ensure the stack is mounted to a proper heat sink or metallic block.

Expected Stack Battery voltages when viewing diagnostics are 6.4Vdc when depleted, 7.4Vdc nominal and 8.0 to 8.4Vdc when fully charged

Repeatedly running the "Test All" on the Diagnostics tab should give an indication that charging is active

A battery reporting a voltage of less than 4.4V has a bad internal cell (two cells per stack battery) and needs service

Two settings in SLICEWare.exe.config that control the error reporting in diagnostics:<setting name="DiagnosticsBatteryVoltageLow" serializeAs="String"><value>8</value><setting name="DiagnosticsBatteryVoltageHigh" serializeAs="String"><value>9</value>

One settings in SLICEWare.exe.config that controls the arm status and controls the level that the hardware will fault. If you have a stack battery in your test that has a voltage below this threshold the SLICE will fault immediately when arming, red STS LED: <setting name="AcquireForm_BatteryVoltageLow" serializeAs="String"> <value>7.8</value>
